Abstract
The invention relates to a novel motor rotor structure comprising a punching sheet with the circular shape, and the inner circumference of the punching sheet is provided with positioning keys. The outer circumference of a rotor frame is provided with positioning key grooves matching with the positioning keys, and the punching sheet and the outer circumference of the rotor frame are in fit clearance; a plurality of inserting grooves allowing a magnetic steel to insert are arranged on the circumference of the punching sheet, the magnetic steel and the punching sheet are in fit clearance, and plastic rubber is injected in the clearance between two ends of the magnetic steel and the punching sheet. Since the punching sheet and the rotor frame are in fit clearance, the punching sheet and the rotor frame can be fixed tightly while the punching sheet is free of being pressed by a baffle; the magnetic steel and the punching sheet are in fit clearance, the plastic rubber is injected in the clearance between the magnetic steel and the punching sheet to fix the magnetic steel, the ends of the magnetic sheets are free of being shielded by the baffle, the magnetic steel can be applied to the motor rotor assembly directly, the occupied space is small, the rotor structure is simple, the space of the motor is saved effectively, material cost is saved, and the assembling efficiency of the rotor is improved.
Description
Technical field
The present invention relates to rotor technical field, especially a kind of Novel motor rotor structure.
Background technology
Along with Global Auto recoverable amount strengthens further, the problems such as energy crisis, environmental pollution and global warming become increasingly conspicuous, new-energy automobile, and especially hybrid vehicle becomes the emphasis of domestic and international motor corporation development.No matter from environmental angle or from energy angle, following hybrid vehicle all needs a large development, and it develops the ups and downs that will be related to numerous industry, may become following new growth engines.In China, hybrid vehicle more has unique market, and metropolis all ubiquity very serious traffic problems and motor vehicle exhaust emission pollution problem.As the daily vehicles that a kind of miniature energy-saving reduces discharging, hybrid vehicle is very good, and it has advantageous development condition and wide application prospect in China.
Conventional ADS driving motor in the market, its rotor tip is provided with baffle plate, baffle plate is arranged on rotor field spider by bolt, for blocking magnet steel and punching, its volume is large, have following open defect: 1) wasting space, for the driving assembly that car load is compact, baffle plate adds engine bin space requirement; 2) waste material, because rotor has magnet steel, baffle plate must adopt non-magnetic precious metal material; 3) be unfavorable for that rotor assembles, add assembly difficulty and operation, reduce efficiency of assembling; 4) bolt easily comes off, and cannot realize closely fixing.
Summary of the invention
The object of the present invention is to provide that a kind of structure is simple, cost is low, effective saving motor space, improve the Novel motor rotor structure of rotor efficiency of assembling.
For achieving the above object, present invention employs following technical scheme: a kind of Novel motor rotor structure, comprising profile is circular punching, its inner circle arranges positioning key, the outer ring of rotor field spider is offered the positioning spline matched with positioning key, the outer ring interference fit of punching and rotor field spider, punching offers multiple slot inserted for magnet steel with it along its circumference week, magnet steel and punching interference fit, fill mould-injection in the slot gap between the magnet steel and punching at magnet steel two ends.
The outer ring of described rotor field spider is the ring-type barricade be arranged on rotor field spider, and the inner headed face of described punching and the periphery of ring-type barricade fit tightly, and the positioning key be arranged in punching inner circle matches with the positioning spline be opened on ring-type barricade.
The section shape of described slot is roughly in up-narrow and down-wide rectangle, and the length of slot is greater than the length of magnet steel, and the groove depth of slot is consistent with the width of magnet steel, and the height of slot is consistent with the height of magnet steel.
The cross section of described magnet steel is rectangular.
Described slot equidistantly distributes along the circumference of punching.
As shown from the above technical solution, the punching in the present invention by with rotor field spider interference fit, without the need to baffle plate compress punching punching and rotor field spider just can be made closely to be fixed together; Interference fit between magnet steel and punching and pour into mould-injection with fixing magnet steel in the two gap, magnet steel end is blocked without the need to baffle plate, can be applied directly on Rotor Assembly, take up room little, make rotor structure simple, effective saving motor space, saves material cost, improves the efficiency of assembling of rotor.

Embodiment
A kind of Novel motor rotor structure, comprising profile is circular punching 20, its inner circle is arranged positioning key 21, the outer ring of rotor field spider 30 is offered the keyway 31 matched with positioning key 21, the outer ring interference fit of punching 20 and rotor field spider 30, punching 20 offers multiple slot 22 inserted for magnet steel 10 with it along its circumference week, magnet steel 10 and punching 20 interference fit, mould-injection 40 is filled, as shown in Fig. 1,2,5 in slot 22 gap between the magnet steel 10 and punching 20 at magnet steel 10 two ends.
As shown in Fig. 1,4, the outer ring of described rotor field spider 30 is the ring-type barricade 32 be arranged on rotor field spider 30, the inner headed face of described punching 20 and the periphery of ring-type barricade 32 fit tightly, and the positioning key 21 be arranged in punching 20 inner circle matches with the keyway 31 be opened on ring-type barricade 32.As shown in Figure 3, described slot 22 equidistantly distributes along the circumference of punching 20, the section shape of described slot 22 is roughly in up-narrow and down-wide rectangle, the length of slot 22 is greater than the length of magnet steel 10, the groove depth of slot 22 is consistent with the width of magnet steel 10, the height of slot 22 is consistent with the height of magnet steel 10, and the cross section of described magnet steel 10 is rectangular.
In rotor assembling process, by press, punching 20 is pressed into rotor field spider 30 outer ring, punching 20 and rotor field spider 30 interference fit, key connects location; Press is used to be pressed in the slot 22 of punching 20 by magnet steel 10 again; Finally by frock, mould-injection 40 is poured in the gap between punching 20 and magnet steel 10.
